Best AI agent memory tools in 2026
Blog post from Braintrust
AI agent memory tools enhance the capability of language models by providing persistent recall across sessions, thereby allowing agents to remember preferences, project details, and decisions beyond the active context window. These tools store extracted facts in a separate memory layer and retrieve relevant information when new requests rely on previous context. Several tools, such as Mem0, Zep, Letta, Supermemory, Cognee, and Sentra, offer various approaches to managing memory, including semantic retrieval, temporal knowledge graphs, and agent-managed memory blocks. Each tool has distinct features tailored to specific use cases, such as personalization, support workflows, or organizational knowledge sharing. Integrating these tools can transform how agents handle long-term memory, but the effectiveness of memory enhancements should be evaluated through comparison tests that assess continuity, error reduction, and task completion across sessions.
